Breeding method and matters needing attention of Acer truncatum Bunge

The breeding method of Acer truncatum is to select suitable strong seedlings and plant them in pots; The matters needing attention in aquaculture are proper illumination and reasonable fertilization.

First, the breeding method of Castanea henryi

1, select the appropriate strong seedlings.

Acer truncatum can be used for cutting or climbing with low and twisted strong seedlings when making bonsai. Novices suggest using seedlings to cultivate miniature Acer truncatum bonsai, which is cheap in source and easy to raise and live.

2. Planting in the upstream basin

Castanea henryi likes loose, fertile, moist, organic-rich, well-drained neutral soil or slightly acidic soil. Pot soil can be mixed with 7 layers of humus soil and 3 layers of sand, which can be used after disinfection. If it is a big seedling, you need to cut off the roots, cut off the long main roots and thick roots, and leave more fine roots. If the root system is ornamental, it can be uprooted year by year. Pay attention to the close combination of root system and soil when planting, and don't curl, empty drum or leave root blank. After planting, water the roots and leave them in the shade 1-2 weeks.

Second, matters needing attention in Castanea henryi cultivation

1, suitable lighting

Acer truncatum is a weakly positive tree species, which is tolerant to semi-shade. It is easy to get sunburned when planted alone in direct sunlight in summer. It can be cultivated in balcony or courtyard in spring and autumn, and moved to semi-shade in summer. Pay attention to proper shading to prevent the edges of leaves from being scorched by the hot sun. If you want to watch it indoors, you should put it in a well-lit place and pay attention to air circulation. After being left for a period of time, it should be moved to an outdoor sunny place for cultivation.

2. Rational fertilization

Potted Acer truncatum generally begins to germinate in spring and applies pancake fertilizer 1 time every month, and then changes to potash fertilizer in September. If 0.5%- 1% potassium sulfate solution or plant ash extract is applied, the leaves will be brighter.

Pruning method of Castanea henryi

Acer truncatum is a small deciduous tree with umbrella-shaped crown, smooth bark, dark gray color and purple or light green branchlets. Pruning Acer truncatum should avoid the growth period, otherwise it will easily affect the overall growth of the plant and be unfavorable to the later growth. Moreover, Acer truncatum is usually pruned after defoliation. At this time, the temperature is low and the plants grow slowly. Pruning can not only reduce the loss of water and nutrients, but also reduce the damage to Acer truncatum.

Cut off unhealthy, overlapping, withered, weak and trailing branches of Acer truncatum with disinfection scissors, and cut short long branches and sparse branches to reduce nutrient consumption and improve ventilation between branches and leaves. In addition, when the annual seedlings grow to 30-50 cm, topping should be carried out.
